To allfwliomitmayc0iwe1"lif' Be it known that I DE ROY AUSTIN, a citizenof the United tates, and a resident of Omaha, in the county of D011 las.and

State of Nebraska, vhave invente ,cert-ain new and useful Improvementsin Insoles for Shoes, of which the following is a speci- 1 lication. ,y

My invention relates to insolesforboots and shoes, and itis the objectthereof-to provide in a boot or shoe an-insole ofrela'f tively heavymaterial having transverse reduced portions 'by which the same isrendered flexible, and having sai-d 'trans--v verse reduced Aportionsreinforced byffresili-l enty material so that the insole will not *beweakened and alsoto that the soles thereof be madeliexible so as to bendeasily and permit a natural move ment of the foot. in 'walking 'Suche'ilexibility is` ordinarily attained Iby the 'use of thin soles andinsoles,` but the use of thin material, especially for insoles,isobjectionablefor the reason'that at the edges of the sole where it isattached to 'the upper and welt there is insufficient material to givethe necessary strength. As a result the insole thus lackingindurability. lIt is also de-I sirablein shoes having cushioned insolesthat the cushioning material be so held inl position as to overcome anytendency there- 1 of to bunch orlump, thereby becoming thinner at thepoints which receive the greatest pressure and thicker at those partswhich receive lighter ressures. l

My invention provi es a means for attain ing the above desired results.1

In the accompanying drawings, Figure 1' is a partial' longitudinalvertical section the sole, so that at the edges ofthe s'ole through ashoe having an insole constructed in accordance with `my invention, Fig.2 4is a transverse vertical section ofthe same on the plane of the line.of Fig. 1, and Fi 3 is a bottom. plan of the insole and we t with theoutsole-removed therefrom.

wherethe same are secured-,to the.welt and upperthere isample materialto makea strongand durablevseam. :In the front part of the insole, or`fromthe instep to the toe, a number of .transverse channelsI o rgrooves are made in the lower side thereof, the. said channels being ofuniform depth and the width thereof beingsolnewhat greater than. that oftheA transverse-tongues or ribsl 'of The said strips of material arerect-angular in 4 section'and the normal thickness-thereofis'-madegreaterthan theqdepth ofthe trans verse channels so that when thematerial is vcompressed itl will as nearly asv possible 'just. lill' thechannels and the lower surface there-y form to the outline ofthe`sole,as shownin `,The ends ofy the strip's 4'are shapedto con igFig. 3, the said strips andthe channels terf'- ',minatinginside thefeather 7 vthrough which the insole is sewed to the upper andA welt.`

Between lthe insole and outsole a thinsheet .8 of felt orI othersuitable l'material maybe i' f placed, 'and when such sheet i'sused' thevsame is ,preferably cemented in place.'y soon givesway at the edges andthe shoe is It willbe'obvious that by the construction" shown a shoe maybe provided with a heavy i and durable insole which may be readily..

flexed or bent Vto accommodate the natural bending movement of the footin walking. The sole rat the thinnedv or weakened portions thereof madeby the transversefchannels -is sustained by the stripsf ofresilient derthe points ofgreatest pressure so as to conform to'the shape of, the'foot and provide, a cushioned or resilient tread,and that the strips ofresilient materialare 4so heldin that Athe same cannotL be displaced' orthe cushioning material become unevenlyf dls-v tributed as is liable incushioned soles wherev material is not so held to its' the cushioningproper position.

"Now, having described my invention,what

I claim and desire to secure by Letters Patent is:
